A signal sent from an iPhone brought the last of 382 solar trackers into position perpendicular with the sun and marked the commissioning of what developers say is the largest solar installation in Vermont and the largest installation of its kind in North America.
The project unveiled Wednesday uses 382 AllSun Trackers produced by Williston-based AllEarth Renewables. The pole-mounted trackers use global positioning systems and wireless technology to follow the sun throughout the day, producing more than 40 percent more energy than fixed solar.
Company officials say that with inverters on each solar tracker to boost energy performance, the project is the largest solar installation to use such a configuration in North America. Gov. Peter Shumlin and other officials attended the unveiling on Wednesday.
